Studies that expand the scope of the Prins-pinacol synthesis of carbocyclicring systems are described. The construction of cyclopentacyclooctanones by ring-enlarging cyclopentane annulations of cycloheptanone precursors is broadly examined as is the synthesis of related bicyclic ketones containing larger rings. Prins-pinacol reactions of acyclic alkenyl acetals were examined to gain insight into intrinsic

[GRAPHICS]A new one-pot synthesis of pyrrole derivatives from ketone hydrazone has been developed by aerobic oxidation of functionalized gem-Zn/Sn dimetallic species, which are prepared by the carbometalation reaction of zincated hydrazone with vinylstannane.
